CVE-2026-3888 1 Canonical 1 Ubuntu Linux 2026-06-04 N/A 7.8 HIGH
Local privilege escalation in snapd on Linux allows local attackers to get root privilege by re-creating snap's private /tmp directory when systemd-tmpfiles is configured to automatically clean up this directory. This issue affects Ubuntu 16.04 LTS, 18.04 LTS, 20.04 LTS, 22.04 LTS, and 24.04 LTS.
CVE-2022-0492 6 Canonical, Debian, Fedoraproject and 3 more 33 Ubuntu Linux, Debian Linux, Fedora and 30 more 2026-06-03 6.9 MEDIUM 7.8 HIGH
A vulnerability was found in the Linux kernel’s cgroup_release_agent_write in the kernel/cgroup/cgroup-v1.c function. This flaw, under certain circumstances, allows the use of the cgroups v1 release_agent feature to escalate privileges and bypass the namespace isolation unexpectedly.
CVE-2026-3497 4 Canonical, Debian, Openbsd and 1 more 4 Ubuntu Linux, Debian Linux, Openssh and 1 more 2026-06-02 N/A 7.5 HIGH
Vulnerability in the OpenSSH GSSAPI delta included in various Linux distributions. This vulnerability affects the GSSAPI patches added by various Linux distributions and does not affect the OpenSSH upstream project itself. The usage of sshpkt_disconnect() on an error, which does not terminate the process, allows an attacker to send an unexpected GSSAPI message type during the GSSAPI key exchange to the server, which will call the underlying function and continue the execution of the program without setting the related connection variables. As the variables are not initialized to NULL the code later accesses those uninitialized variables, accessing random memory, which could lead to undefined behavior. The recommended workaround is to use ssh_packet_disconnect() instead, which does terminate the process. The impact of the vulnerability depends heavily on the compiler flag hardening configuration.
CVE-2026-47335 1 Canonical 1 Ubuntu Linux 2026-05-29 N/A 5.5 MEDIUM
Ubuntu Linux 6.8 contains SAUCE patches with a possible NULL pointer dereference in the handling of AppArmor notifications. The bug can be triggered by an unprivileged local user. This can lead to a kernel panic.
CVE-2026-47336 1 Canonical 1 Ubuntu Linux 2026-05-29 N/A 3.3 LOW
Ubuntu Linux 6.8 contains SAUCE patches with a possible use of an uninitialized variable in AppArmor AF_INET/AF_INET6 socket mediation code. The bug can be triggered by an unprivileged local user and could result in incorrect fine-grained mediation of network sockets.
CVE-2026-47337 1 Canonical 1 Ubuntu Linux 2026-05-29 N/A 3.3 LOW
Ubuntu Linux 6.8, 6.17 and 7.0 contain SAUCE patches with a possible NULL pointer dereference in the handling of AF_INET/AF_INET6 socket mediation. The bug can be triggered by an unprivileged local user. This can lead to a kernel oops.
CVE-2018-3639 12 Arm, Canonical, Debian and 9 more 321 Cortex-a, Ubuntu Linux, Debian Linux and 318 more 2026-05-29 2.1 LOW 5.5 MEDIUM
Systems with microprocessors utilizing speculative execution and speculative execution of memory reads before the addresses of all prior memory writes are known may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis, aka Speculative Store Bypass (SSB), Variant 4.
CVE-2018-13785 4 Canonical, Libpng, Oracle and 1 more 7 Ubuntu Linux, Libpng, Jdk and 4 more 2026-05-29 4.3 MEDIUM 6.5 MEDIUM
In libpng 1.6.34, a wrong calculation of row_factor in the png_check_chunk_length function (pngrutil.c) may trigger an integer overflow and resultant divide-by-zero while processing a crafted PNG file, leading to a denial of service.
CVE-2020-29372 2 Canonical, Linux 2 Ubuntu Linux, Linux Kernel 2026-05-29 4.7 MEDIUM 4.7 MEDIUM
An issue was discovered in do_madvise in mm/madvise.c in the Linux kernel before 5.6.8. There is a race condition between coredump operations and the IORING_OP_MADVISE implementation, aka CID-bc0c4d1e176e.
CVE-2019-7317 11 Canonical, Debian, Hp and 8 more 33 Ubuntu Linux, Debian Linux, Xp7 Command View and 30 more 2026-05-28 2.6 LOW 5.3 MEDIUM
png_image_free in png.c in libpng 1.6.x before 1.6.37 has a use-after-free because png_image_free_function is called under png_safe_execute.
CVE-2019-6109 9 Canonical, Debian, Fedoraproject and 6 more 28 Ubuntu Linux, Debian Linux, Fedora and 25 more 2026-05-28 4.0 MEDIUM 6.8 MEDIUM
An issue was discovered in OpenSSH 7.9. Due to missing character encoding in the progress display, a malicious server (or Man-in-The-Middle attacker) can employ crafted object names to manipulate the client output, e.g., by using ANSI control codes to hide additional files being transferred. This affects refresh_progress_meter() in progressmeter.c.
CVE-2019-18197 4 Canonical, Debian, Linux and 1 more 4 Ubuntu Linux, Debian Linux, Linux Kernel and 1 more 2026-05-28 5.1 MEDIUM 7.5 HIGH
In xsltCopyText in transform.c in libxslt 1.1.33, a pointer variable isn't reset under certain circumstances. If the relevant memory area happened to be freed and reused in a certain way, a bounds check could fail and memory outside a buffer could be written to, or uninitialized data could be disclosed.
CVE-2019-17571 6 Apache, Canonical, Debian and 3 more 17 Bookkeeper, Log4j, Ubuntu Linux and 14 more 2026-05-28 7.5 HIGH 9.8 CRITICAL
Included in Log4j 1.2 is a SocketServer class that is vulnerable to deserialization of untrusted data which can be exploited to remotely execute arbitrary code when combined with a deserialization gadget when listening to untrusted network traffic for log data. This affects Log4j versions up to 1.2 up to 1.2.17.
CVE-2019-16168 8 Canonical, Debian, Fedoraproject and 5 more 20 Ubuntu Linux, Debian Linux, Fedora and 17 more 2026-05-28 4.3 MEDIUM 6.5 MEDIUM
In SQLite through 3.29.0, whereLoopAddBtreeIndex in sqlite3.c can crash a browser or other application because of missing validation of a sqlite_stat1 sz field, aka a "severe division by zero in the query planner."
CVE-2019-13118 7 Apple, Canonical, Fedoraproject and 4 more 25 Icloud, Iphone Os, Itunes and 22 more 2026-05-28 5.0 MEDIUM 5.3 MEDIUM
In numbers.c in libxslt 1.1.33, a type holding grouping characters of an xsl:number instruction was too narrow and an invalid character/length combination could be passed to xsltNumberFormatDecimal, leading to a read of uninitialized stack data.
CVE-2019-13117 6 Canonical, Debian, Fedoraproject and 3 more 6 Ubuntu Linux, Debian Linux, Fedora and 3 more 2026-05-28 5.0 MEDIUM 5.3 MEDIUM
In numbers.c in libxslt 1.1.33, an xsl:number with certain format strings could lead to a uninitialized read in xsltNumberFormatInsertNumbers. This could allow an attacker to discern whether a byte on the stack contains the characters A, a, I, i, or 0, or any other character.
CVE-2019-11135 9 Canonical, Debian, Fedoraproject and 6 more 304 Ubuntu Linux, Debian Linux, Fedora and 301 more 2026-05-28 2.1 LOW 6.5 MEDIUM
TSX Asynchronous Abort condition on some CPUs utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access.
CVE-2019-11068 7 Canonical, Debian, Fedoraproject and 4 more 22 Ubuntu Linux, Debian Linux, Fedora and 19 more 2026-05-28 7.5 HIGH 9.8 CRITICAL
libxslt through 1.1.33 allows bypass of a protection mechanism because callers of xsltCheckRead and xsltCheckWrite permit access even upon receiving a -1 error code. xsltCheckRead can return -1 for a crafted URL that is not actually invalid and is subsequently loaded.
CVE-2017-5753 13 Arm, Canonical, Debian and 10 more 387 Cortex-a12, Cortex-a12 Firmware, Cortex-a15 and 384 more 2026-05-28 4.7 MEDIUM 5.6 MEDIUM
Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis.
CVE-2015-2808 9 Canonical, Debian, Fujitsu and 6 more 99 Ubuntu Linux, Debian Linux, Sparc Enterprise M3000 and 96 more 2026-05-28 5.0 MEDIUM 3.7 LOW
The RC4 algorithm, as used in the TLS protocol and SSL protocol, does not properly combine state data with key data during the initialization phase, which makes it easier for remote attackers to conduct plaintext-recovery attacks against the initial bytes of a stream by sniffing network traffic that occasionally relies on keys affected by the Invariance Weakness, and then using a brute-force approach involving LSB values, aka the "Bar Mitzvah" issue.
